RevBurn ReviewRevBurn is a fat burning supplement and thermogenic developed by Rev Labs. It has been formulated to increase energy and endurance, provide appetite suppression and control and support metabolic optimization.

Stimulants Are a Part of the Formula

One of the first aspects about this dietary supplement that you should know before you decide to purchase and try it is that RevBurn does contain more than one stimulant. Most notably it contains caffeine, phenylethylamine HCl and kola nut.

On the plus side, stimulants like caffeine are known to have an effect on the central nervous system. It is commonly believed that caffeine’s ability to elevate mood and metabolism could have a positive effect on individuals who are seeking to burn fat for weight loss.

For instance, one study suggests that when caffeine is ingested prior to aerobic exercise it can increase fat loss.

On the downside, there is no guarantee that ingesting caffeine, either via RevBurn or through other drinks or foods, will result in fat loss that will lead to measurable and long-term weight loss.  Additionally, caffeine and other stimulants can cause unwanted side effects, such as:

  • Jitters
  • Rapid heartbeat
  • Sleep disturbances
  • Anxiety
  • Headache

Additionally, to decrease the potential risk of unwanted side effects, such as sleep disturbances, avoid taking these pills too late in the afternoon or the evening.

What Else to Consider

The makers of RevBurn say that when it is combined with exercise and a reduced calorie diet, it can help a user reach their weight loss goals as the ingredients within the formula can boost metabolism and fat-burning for up to 8 hours.

There is no clinical proof that this claim is true. Moreover, you should not assume that simply because this is a nonprescription weight loss aid that it is safe to take. If you have an existing medical condition, are taking prescription or over the counter medications or herbal supplements to treat a health issue, or are pregnant or nursing, you should consult with your doctor before taking RevBurn diet pills.

Prime Labs Thermo Burn

Prime Labs Thermo Burn ReviewSeeking extreme weight loss? Prime Labs Thermo Burn claims to provide this benefit by supporting appetite suppression, energy levels and weight loss. Part of Prime Labs’ Elite Series, Thermo Burn has been designed to work with your existing diet and exercise routine to help you achieve results.

At the time that this Prime Labs Thermo Burn review was written, the formula was composed of Green Coffee Bean, Raspberry Ketone, Garcinia Cambogia, Caffeine Anhydrous, Green Tea.

For optimal results, it is always important to take any product as directed based on the manufacturer’s suggestion or as directed by your healthcare provider. For Thermo Burn, the suggested use is to take 1 capsule twice daily, 20-30 minutes before a meal with an 8 ounce glass of water.

The three main ingredients in this formula are caffeine (also found in green coffee bean and green tea), raspberry ketone and garcinia cambogia.

Caffeine is a central nervous system stimulant that can raise blood pressure and can also act like a diuretic, increasing the frequency of urination. However, these effects are not typically common in people who take caffeine regularly. It is likely effective for increasing mental alertness and may also help to improve athletic performance. Some research has also found that caffeine may decrease appetite in some people.

Garcinia cambogia is thought to help prevent fat storage, suppress appetite and increase exercise endurance. Although it is not known if these effects occur in humans. As for raspberry ketones, it is thought to help increase the rate at which the body burns fat and may reduce appetite. That being said, just like garcinia cambogia there is no scientific evidence that raspberry ketone improves weight loss in humans.

While it is highly unlikely that you will experience extreme weight loss with Thermo Burn, you are likely to feel its stimulant effects as it contains caffeine, and substance that contain caffeine, green tea and green coffee bean. Although this could lead to benefits such as enhanced mental alertness, it may also lead to unpleasant side effects, such as anxiety, jitters, restlessness, headache, heart palpitations, rapid heartbeat, insomnia, and digestive upset.

Individuals who are sensitive to caffeine, or who consume other products containing caffeine while taking this diet pill, are at an increased risk of these adverse effects.

Be sure to speak with your healthcare provider before taking Prime Labs Thermo Burn, especially if you have an existing health condition and/or are currently taking any medications (prescription or non-prescription) or other herbal supplements.


Stacker3 ReviewStacker3 with chitosan is a diet and energy supplement and metabolizing fat burner. It is a Stacker2 product and has a new formula that is now free of ephedra. The ingredients selected for the new formula may create a thermogenic response and deliver a boost of energy.

As previously mentioned, Stacker3 contains chitosan. This is a fibrous substance that is extracted from the shells of crustaceans, such as lobster, crab and shrimp. It is thought that it may block the absorption of dietary fat and cholesterol. As it can’t be properly digested by the body, it passes through the digestive tract, potentially bonding with ingested fat along the way, and carries it out as it is expelled from the body as waste.

That being said, there is more than just chitosan in Stacker3. When this review was written, the formula contained the following: Chromium, Proprietary Blend (Green Tea, Taurine, Garcinia Cambogia, White Willow Bark, Chitosan), Caffeine.

Based on the ingredients, it’s clear that the developers of Stacker3 were focused on including substances that are thought to help with appetite control, increased mental focus, energy boosting, metabolism boosting, increasing thermogenesis, and preventing the body from ingesting a certain amount of fat.

With that in mind, however, even though these ingredients may have the potential to help a person with their efforts to lose weight, this doesn’t meant that they actually will. The reason is simple: neither these ingredients nor Stacker3 have been scientifically proven for causing weight loss.

Moreover, it may not be in your best interest to take Stacker3, due to its high caffeine content. The suggested use is to take 1 capsule after meals, but not to exceed 3 pills in a 24 hour period. Considering Stacker3 contains 250 mg of caffeine per serving, which is about equal to 3 cups of coffee, the maximum 3 capsule dose would be equal to drinking 9 cups of coffee in a day! Needless to say, this is an extremely high dose of caffeine, which calls into question the integrity and safety of this product.

Such high doses of caffeine are bound to lead to adverse effects, even in people who are not typically sensitive to this stimulant. Such effects may include insomnia, anxiety, jitters, heart palpitations, rapid heartbeat, headache, high blood pressure, etc.

Also, be advised that chitosan comes from shellfish. If you have an allergy to shellfish, do not take this product or any other dietary supplement that contains chitosan.

Ultimately, however, because of the caffeine content in Stacker3 it would be best if you avoided this diet pill and found a safer alternative.

Codeage Keto Carb Blocker

Codeage Keto Carb Blocker ReviewCodeage Keto Carb Blocker is an extra strength dietary supplement for weight loss designed to block carbohydrate absorption into the body. This over-the-counter (OTC) weight management product is manufactured by Codeage.

White Kidney Bean (500 mg), Green Tea (250 mg), and Cinnamon Powder (200 mg) were the active ingredients in Codeage Keto Carb Blocker when this review was written.

Each of these ingredients was carefully selected for the formula as each one has potential benefits that can be very helpful with weight management.

For instance, white kidney beans are believed to help the body block the absorption of starch. More specifically, it helps prevent carbohydrates from breaking down and converting into fat and sugar. That being said, research has shown that in spite of these claims, white kidney bean does not seem to lower the absorption of starch.

Green tea is said to help with appetite and cravings and also gives your mood a boost. Research has found that the caffeine in green tea may improve mental alertness and may help to increase weight loss in obese adults. That being said, there is a lot of conflicting research regarding green tea and weight management. Further research needs to be conducted to determine its true benefits.

Cinnamon is believed to offer many health benefits. Among these include the regulation of blood sugar levels and lowering high cholesterol. Although some research suggests that cinnamon can effect blood sugar levels, there is conflicting evidence regarding its overall effect on blood sugar.

What all this means is that Codeage Keto Carb blocker contains clinically researched ingredients. However, whether or not these ingredients can actually offer any real benefits to individuals seeking to reduce fat and trim their waistlines, is unknown. In short, there is no guarantee that Codeage Keto Carb Blocker can live up to its claims.

Nonetheless, be advised that if you are intending to take this dietary supplement, be sure to follow the directions (either the manufacturer’s or your doctors) accurately. The recommended use is to take 2 capsules daily with 8 ounces of water or your favorite beverage. It can be taken with or without food. Also, for optimal results, Codeage does say that following a low carb, ketogenic diet may help a user experience even better results with this carb blocker.

As with any dietary supplement, it is always in your best interest to first consult with your medical practitioner before you make Codeage Keto Carb Block a part of your weight management regimen.

Body Perfect Acai Berry & Green Tea 1:1

Body Perfect Acai Berry & Green Tea 11 reviewBio-Synergy Ltd has a large category of dieting and weight loss supplements, and Body Perfect Acai Berry & Green Tea 1:1 is among those that it claims is not only for weight but also has health benefits. Among those benefits is, according to the official webpage for the product on the manufacturer’s website, that it contains superfoods, and that it contains anti-carcinogens and anti-oxidants. The claim is that users will start to see noticeable results within a period of one month after starting to use it. That said, it does not specify what results will be seen.

At the time that this review was written, the official webpage for the product listed the ingredients in this formula as being: acai berry extract and green tea extract. It also contained non-medicinal ingredients that make up the capsule, including gelatin, silicon dioxide, and magnesium stearate.

Green tea is an ingredient that has some support from scientific research that shows that its use – in proper amounts – can help to increase the rate of weight loss. That said, those studies were not cited by the official website for this product. They were discovered as a part of the research process while conducting this review. Moreover, the typical study that found that green tea extract could help to improve the rate of weight loss among obese patients used about 500 mg per day. Every Perfect Acai Berry & Green Tea 1:1 capsule contains 1000 mg of green tea and the directions say that 2 capsules should be taken per day. This means that users of this product will receive about four times what many studies found to be effective and safe. For that reason, the results and the potential side effects of using this ingredient may not be the same from this supplement as they were from many of the clinical studies that would support the use of green tea.

It is also worth noting that while acai berry is a substance that is high in antioxidants, which are good for overall health, they have not been directly associated with measurable weight loss by any reputable clinical research. Within the dieting industry, they are much more commonly connected with scams than they are with results. At the same time, it is unlikely that this ingredient would cause any unwanted or dangerous side effects among users of this product, so it could simply provide healthy antioxidants to support the possible weight loss benefits of the green tea.
